OVERVIEW

A wallet that just works.

Sendit is a mobile payment app designed to make money transfers and expense tracking simple, fast, and transparent for everyday users.

PROBLEM

Finance management is fragmented.

People often switch between banking apps, notes, screenshots, and reminders to understand where their money goes. Sendit explores a simpler wallet flow where sending, tracking, and reviewing payments stay in one place.

DESIGN CHALLENGE

How might we design a payment flow that feels fast, but still gives users enough clarity and confidence before, during, and after a transaction?

Make the main balance and actions immediately visible.

Reduce the number of steps needed to send money.
Provide clear confirmation and spending feedback after the transfer.

KEY SCREENS

Designed for clarity at every step.

Home
A clear dashboard gives users quick access to core banking actions and account overview.

Send Money
The transfer flow keeps attention on one task, making payment entry simple and focused.

Contacts
A searchable contact list helps users find recipients quickly and reduces friction in repeat transfers.

Statistics
Spending and income are visualized in a way that makes financial patterns easy to scan.

History
Transaction categories are organized for quick review, helping users understand where money goes over time.

DESIGN PRINCIPLES

Clarity first
The interface prioritizes balance, amount, recipient, and confirmation so users always understand what is happening.

Speed with control
The flow is designed to feel fast, but not careless. Each step gives enough information before the user commits to sending money.

Visible reassurance
Feedback screens, transaction details, and spending summaries help reduce uncertainty after payment actions.

PROCESS

From insight to interface.

01 - Define

Identified three core user needs: send money quickly, track spending by category, view balance at a glance. These became the foundation for every design decision.

02 - Design

Built the information architecture around 4 key actions: Top Up, Transfer, Request, History. Bottom tab navigation keeps movement between screens fast and frictionless.

03 - Visual Design

Purple as the primary brand color to signal trust and modernity. High contrast white cards for readability. Large typography for key financial figures to reduce cognitive load.

OUTCOME

A complete payment experience.

The final prototype covers the essential wallet journey from balance overview to recipient selection, amount entry, transfer confirmation, and spending review.

Rather than designing a full banking product, the project focuses on one clear experience: making everyday payments feel simple, readable, and trustworthy.

What I learned

Designing for money means designing for confidence.

This project helped me understand that financial interfaces are not only about completing actions quickly. They also need to create trust at every step.

Small design decisions — such as hierarchy, spacing, confirmation feedback, and transaction visibility — can strongly affect whether users feel calm, informed, and in control.
